Fujifilm F660EXR has a
16.0MP 1/2-inch (6.4 x 4.8 mm ) sized EXRCMOS sensor and features EXR processor. On the other hand, Nikon D40X has a
10.0MP APS-C (23.7 x 15.6 mm ) sized CCD sensor and features Expeed processor.
Fujifilm F660EXR's sensor provides 6MP more than Nikon D40X's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the F660EXR and D40X sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm F660EXR and Nikon D40X Cameras
As seen above, Nikon D40X has a 12.0x Larger sensor area than Fujifilm F660EXR. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Fujifilm F660EXR
or the
Nikon D40X ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2-inch versus APS-C),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
